It wouldn't be evenly distributed. Your carrier could pass on the fine at least a few hops deep, until it reaches whoever connected the shady VoIP company to the real network. In the video's example, it would be Google Voice, the owner of the hacked VoIP systems' uplink provider, or the anonymous online call services. It's rare that the spammers use payphones or prepaid cards.
Even if it's the same situation as with e-mail spam, this would also be a workable solution for that problem.
Say I have a G-Mail account. I get spam from X@hotmail.com. Now G-Mail have to pay me the fine, and Hotmail have to pay GMail the fine, and X has to pay Hotmail the fine. Sure, they can't track down X, but Hotmail have to pay up for letting bad actors on their network.
We could also generalize this to BGP, of course. I get a port 22 brute-force attempt to my server, I contact my ISP, they pay me. They contact whoever peered them, who pays, until we get to China, where some local ISP says that a PC on their network was hacked. Too bad. Either the Chinese ISP pays up, or they get depeered by their CN <-> HK ISP, or they get depeered by their uplink, and so on.
Here is an example traceroute to the Chinese ecommerce site taobao.com from Cogent. In my example, the fine would travel down this list until it finds someone unwilling to pay up, who then gets depeered.
